We talk about the possibility of reducing fossil fuel use by 80% by 2050 and ramping up renewables at the same time, to help prevent climate change. If we did this, what would such a change mean for GDP, based on historical Energy and GDP relationships back to 1820?
Back in March, I showed you this graph in my post, World Energy Consumption since 1820 in Charts.
Graphically, what an 80% reduction in fossil fuels would mean is shown in Figure 2, below. I have also assumed that non-fossil fuels (some combination of wind, solar, geothermal, biofuels, nuclear, and hydro) could be ramped up by 72%, so that total energy consumption “only” decreases by 50%.
We can use actual historical population amounts plus the UN’s forecast of population growth to 2050 to convert these amounts to per capita energy equivalents, shown in Figure 3, below.
In Figure 3, we see that per capita energy use has historically risen, or at least not declined. You may have heard about recent declines in energy consumption in Europe and the US, but these declines have been more than offset by increases in energy consumption in China, India, and the rest of the “developing” world.
With the assumptions chosen, the world per capita energy consumption in 2050 is about equal to the world per capita energy consumption in 1905.
I applied regression analysis to create what I would consider a best-case estimate of future GDP if a decrease in energy supply of the magnitude shown were to take place. The reason I consider it a best-case scenario is because it assumes that the patterns we saw on the up-slope will continue on the down-slope. For example, it assumes that financial systems will continue to operate as today, international trade will continue as in the past, and that there will not be major problems with overthrown governments or interruptions to electrical power. It also assumes that we will continue to transition to a service economy, and that there will be continued growth in energy efficiency.
Based on the regression analysis:
- World economic growth would average a negative 0.59% per year between now and 2050, meaning that the world would be more or less in perpetual recession between now and 2050. Given past relationships, this would be especially the case for Europe and the United States.
- Per capita GDP would drop by 42% for the world between 2010 and 2050, on average. The decrease would likely be greater in higher income countries, such as the United States and Europe, because a more equitable sharing of resources between rich and poor nations would be needed, if the poor nations are to have enough of the basics.
I personally think a voluntary worldwide reduction in fossil fuels is very unlikely, partly because voluntary changes of this sort are virtually impossible to achieve, and partly because I think we are headed toward a near-term financial crash, which is largely the result of high oil prices causing recession in oil importers (like the PIIGS).
The reason I am looking at this scenario is two-fold:
(1) Many people are talking about voluntary reduction of fossil fuels and ramping up renewables, so looking at a best case scenario (that is, major systems hold together and energy efficiency growth continues) for this plan is useful, and
(2) If we encounter a financial crash in the near term, I expect that one result will be at least a 50% reduction in energy consumption by 2050 because of financial and trade difficulties, so this scenario in some ways gives an “upper bound” regarding the outcome of such a financial crash.
Close Connection Between Energy Growth, Population Growth, and Economic Growth
Historical estimates of energy consumption, population, and GDP are available for many years. These estimates are not available for every year, but we have estimates for them for several dates going back through history. Here, I am relying primarily on population and GDP estimates of Angus Maddison, and energy estimates of Vaclav Smil, supplemented by more recent data (mostly for 2008 to 2010) by BP, the EIA, and USDA Economic Research Service.
If we compute average annual growth rates for various historical periods, we get the following indications:
We can see from Figure 4 that energy growth and GDP growth seem to move in the same direction at the same time. Regression analysis (Figure 5, below) shows that they are highly correlated, with an r squared of 0.74.
Energy in some form is needed if movement is to take place, or if substances are to be heated. Since actions of these types are prerequisites for the kinds of activities that give rise to economic growth, it would seem as though the direction of causation would primarily be:
Energy growth gives rise to economic growth.
Rather than the reverse.
I used the regression equation in Figure 5 to compute how much yearly economic growth can be expected between 2010 and 2050, if energy consumption drops by 50%. (Calculation: On average, the decline is expected to be (50% ^(1/40)-1) = -1.72%. Plugging this value into the regression formula shown gives -0.59% per year, which is in the range of recession.) In the period 1820 to 2010, there has never been a data point this low, so it is not clear whether the regression line really makes sense applied to decreases in this manner.
In some sense, the difference between -1.72% and -0.59% per year (equal to 1.13%) is the amount of gain in GDP that can be expected from increased energy efficiency and a continued switch to a service economy. While arguments can be made that we will redouble our efforts toward greater efficiency if we have less fuel, any transition to more fuel-efficient vehicles, or more efficient electricity generation, has a cost involved, and uses fuel, so may be less common, rather than more common in the future.
The issue of whether we can really continue transitioning to a service economy when much less fuel in total is available is also debatable. If people are poorer, they will cut back on discretionary items. Many goods are necessities: food, clothing, basic transportation. Services tend to be more optional–getting one’s hair cut more frequently, attending additional years at a university, or sending grandma to an Assisted Living Center. So the direction for the future may be toward a mix that includes fewer, rather than more, services, so will be more energy intensive. Thus, the 1.13% “gain” in GDP due to greater efficiency and greater use of “services” rather than “goods” may shrink or disappear altogether.
The time periods in the Figure 5 regression analysis are of different lengths, with the early periods much longer than the later ones. The effect of this is to give much greater weight to recent periods than to older periods. Also, the big savings in energy change relative to GDP change seems to come in the 1980 to 1990 and 1990 to 2000 periods, when we were aggressively moving into a service economy and were working hard to reduce oil consumption. If we exclude those time periods (Figure 6, below), the regression analysis shows a better fit (r squared = .82).
If we use the regression line in Figure 6 to estimate what the average annual growth rate would be with energy consumption contracting by -1.72% per year (on average) between 2010 and 2050, the corresponding average GDP change (on an inflation adjusted basis) would be contraction of -1.07% per year, rather than contraction of -0.59% per year, figured based on the regression analysis shown in Figure 5. Thus, the world economy would even to a greater extent be in “recession territory” between now and 2050.
Population Growth Estimates
In my calculation in the introduction, I used the UN’s projection of population of 9.3 billion people by 2050 worldwide, or an increase of 36.2% between 2010 and 2050, in reaching the estimated 42% decline in world per capita GDP by 2050. (Calculation: Forty years of GDP “growth” averaging minus 0.59% per year would produce total world GDP in 2050 of 79.0% of that in 2010. Per capita GDP is then (.790/ 1.362=.580) times 2010’s per capita income. I described this above as a 42% decline in per capita GDP, since (.580 – 1.000 = 42%).)
Population growth doesn’t look to be very great in Figure 4, since it shows annual averages, but we can see from Figure 7 (below) what a huge difference it really makes. Population now is almost seven times as large as in 1820.
Since we have historical data, it is possible to calculate an estimate based on regression analysis of the expected population change between 2010 and 2050. If we look at population increases compared to energy growth by period (Figure 8), population growth is moderately correlated with energy growth, with an r squared of 0.55.
One of the issues in forecasting population using regression analysis is that in the period since 1820, we don’t have any examples of negative energy growth for long enough periods that they actually appear in the averages used in this analysis. Even if this model fit very well (which it doesn’t), it still wouldn’t necessarily be predictive during periods of energy contraction. Using the regression equation shown in Figure 8, population growth would still be positive with an annual contraction of energy of 1.72% per year, but just barely. The indicated population growth rate would slow to 0.09% per year, or total growth of 3.8% over the 40 year period, bringing world population to 7.1 billion in 2050.
Energy per Capita
While I did not use Energy per Capita in this forecast, we can look at historical growth rates in Energy per Capita, compared to growth rates in total energy consumed by society. Here, we get a surprisingly stable relationship:
Figure 10 shows the corresponding regression analysis, with the highest correlation we have seen, an r squared equal to .87.
It is interesting to note that this regression line seems to indicate that with flat (0.0% growth) in total energy, energy per capita would decrease by -0.59% per year. This seems to occur because population growth more than offsets efficiency growth, as women continue to give birth to more babies than required to survive to adulthood.
Can We Really Hold On to the Industrial Age, with Virtually No Fossil Fuel Use?
This is one of the big questions. “Renewable energy” was given the name it was, partly as a marketing tool. Nearly all of it is very dependent on the fossil fuel system. For example, wind turbines and solar PV panels require fossil fuels for their manufacture, transport, and maintenance. Even nuclear energy requires fossil fuels for its maintenance, and for decommissioning old power plants, as well as for mining, transporting, and processing uranium. Electric cars require fossil fuel inputs as well.
The renewable energy that is not fossil fuel dependent (mostly wood and other biomass that can be burned), is in danger of being used at faster than a sustainable rate, if fossil fuels are not available. There are few energy possibilities that are less fossil fuel dependent, such as solar thermal (hot water bottles left in the sun to warm) and biofuels made in small quantities for local use. Better insulation is also a possibility. But it is doubtful these solutions can make up for the huge loss of fossil fuels.
We can talk about rationing fuel, but in practice, rationing is extremely difficult, once the amount of fuel becomes very low. How does one ration lubricating oil? Inputs for making medicines? To keep business processes working together, each part of every supply chain must have the fuel it needs. Even repairmen must have the fuel needed to get to work, for example. Trying to set up a rationing system that handles all of these issues would be nearly impossible.
GDP and Population History Back to 1 AD
Angus Maddison, in the same data set that I used back to 1820, also gives an estimate of population and GDP back to 1 AD. If we look at a history of average annual growth rates in world GDP (inflation adjusted) and in population growth, this is the pattern we see:
Figure 11 shows that the use of fossil fuels since 1820 has allowed GDP to rise faster than population, for pretty much the first time. Prior to 1820, the vast majority of world GDP growth was absorbed by population growth.
If we compare the later time periods to the earlier ones, Figure 11 shows a pattern of increasing growth rates for both population and GDP. We know that in the 1000 to 1500 and 1500 to 1820 time periods, early energy sources (peat moss, water power, wind power, animal labor) became more widespread. These changes no doubt contributed to the rising growth rates. The biggest change, however, came with the addition of fossil fuels, in the period after 1820.
Looking back, the question seems to become: How many people can the world support, at what standard of living, with a given quantity of fuel? If our per capita energy consumption drops to the level it was in 1905, can we realistically expect to have robust international trade, and will other systems hold together? While it is easy to make estimates that make the transition sound easy, when a person looks at the historical data, making the transition to using less fuel looks quite difficult, even in a best-case scenario. One thing is clear: It is very difficult to keep up with rising world population.
You may have a look at Jean-Marc Jancovici work, who propose a very simple equality patterned after Kaya equation to link GBP and energy :

It seems compliant with your own result.
Thanks very much. There are a lot of similarities with respect to what he is writing. He even put together some similar graphs to mine, but with somewhat different sources. He also adds things I didn’t know about.
I think a summing up of Gail’s excellent and thought provoking post would be to observe that mankind has spent all of recorded history, and maybe a million years before that, fighting over resources when the planet had plenty of everything for everybody
Now that we really are running out of everything, don’t expect man to become benevolently inclined towards his fellow man
As James Lovelock so eloquently put it: Man is a tribal carnivore, not a gentle gardener.
That’s a good way of putting it.

Just as an aside: the sorts of scenarios we have been discussing – isolation from power water food and electricity and any other means to transport them into an urban space are happening right now in Aleppo, in Syria.
Those who think ‘we could do without them’, should observe carefully as this drama unfolds.
I had never noticed this coincidence before, but modern Permaculture was born the same year as ASPO–2002. Both were a response to energy descent. Recent books by Akelett and the ASPO conference in Vienna covered the history from that angle. Here is the history from the Permaculture angle, courtesy of Peter Bane, page 29 in Garden Farming:
In 2002, David Holmgren, permaculture’s younger and quieter co-author, reentered the global permaculture conversation decisively with the publication of a new book. While this book had much to say about the evolution of the permaculture system of design and permaculture’s impact on the culture of energy descent–a phrase of David’s coinage–it most decisively established a template of working principles that has gradually taken precedence over the hodgepodge of good ideas, aphorism and guides for the designer that had gone by the name principles up to that time. David’s increasingly visible teaching and writing work, disseminated through his world travels, his books, and over the Web, has persuaded many second and third generation teachers as well as newer students to bring that conceptual lens into focus through practice.
And then, on the facing page, Peter presents David’s conceptual scheme in the form of a repeating cycle, or spiral pattern with his own unique graphics.
If I were to grossly oversimplify ASPO and Holmgren style Permaculture, I would say that ASPO is about hand-wringing while David is about designing to solve problems by mimicking natural processes. The difference in messages is pretty stark: ‘We are all going to die’ vs. ‘We can live pretty well, just differently’. Of course, neither camp is immune to ‘confirmation bias’. But there is no doubt in my mind that I want to be on the side of doing something.
I have looked up one reference in terms of Britain feeding itself. The author is Simon Fairlie and the book is Meat, A Benign Extravagance. The book is endorsed by many notables.
In the chapter Can Britain Feed Itself, he looks at various scenarios and shows what the land utilization would look like under each, along with some reflections about how each scenario would play out in terms of culture change. For the details, you can read the book–and I warn you there is an abundance of detail. But for a flavor of what is possible, here is how he describes A Permaculture Approach:
My main purpose in Tables F and G is to go a step further and see whether the UK could become more self reliant, not only in food, fodder and fertility, but also in fibre and fuel. Our environmental footprint currently stretches across untold ghost acres around the world; if suddenly we had to shoehorn it into the 22 million hectares of non-urban land we have in this country, how would we cope? Could this be done organically, whilst keeping a reasonable amount of meat in our diet for those who wanted it, and ensuring that a reasonable proportion of the country is reserved for wildlife?
Tables F and G reflect a more permacultural approach, by which I mean permaculture on the macro-scale, involving increased integration of lifestyle with natural and renewable cycles, rather than just mulching, intercropping, and herb spirals. Some of the measures taken require a change in our land management systems, and also in human settlement patterns. This is a society in a state of energy descent, with increasing dependence upon renewable resources, more waste cycling and (consequently) a localized economy which is more integrated with natural processes. The approach towards livestock is a default strategy in respect of the cows, insofar as they are grass fed and contribute to the fertility building of the arable rotation; but less so as regards the pigs and chickens since a certain amount of grain is grown to feed them (though in the next chapter I argue that a certain amount of livestock grain is necessary for food security reasons).
The system uses 7.9 million hectares for arable and ley, 5.9 million hectares of permanent pasture, 6 million hectares of woodland, and 2.4 million spare hectares. The system calls for a considerable movement of people from urban areas to the countryside, with considerably more labor involved in agriculture than presently.
Back to me. Britain is one of the more densely populated places on earth. And it clearly can feed itself–just not with the current agricultural system. It also, as is shown by Fairlie, cannot grow enough biofuels to replace fossil fuels and also grow food enough to feed the population. Fairlies’ biofuels scenarios are pretty modest and involve things like farms producing fuel for tractors and heating around 6 million homes with wood (probably the people who move from urban to countryside dwellings). He also shows how the integration of animals into the production cycle increases the efficiency of land use–when done intelligently.
I remain skeptical. I would like to see this actually done in practice, in a reasonable sized area. Or at least reviewed by someone with practical experience.
Waterfall is irregular. I think we should assume people will not be able to water the Permaculture (or if they do, someone is going to a well, raising a bucket from many feet down, transferring the water to jars, and taking the jars to water the plants).
If we don’t have fences (except hedges or rough hewn wood ones, and nets to keep out birds, or refrigeration, there is going to be a lot of crop loss. Has this been factored in?
Fairlie’s scenarios are not complete. For example, I see no evidence that he counts in the oats eaten by the horses that take the food to the cities. And he (and others who have studied the problem) can make some simplifying assumptions such as that everyone in the cities just grows most of their own fruits and vegetables in gardens and allotments. There ARE and HAVE BEEN instances where cities grew most of their own fruits and vegetables. Fruits and vegetables are also the most perishable (full of water) products, and harvesting them when you want to eat them by walking out to your garden makes a lot of sense.
As for trying it out. That is impossible so long as the fossil fuel economy continues to stumble along. If you tried to live this way, you would go broke trying to compete with the subsidized, polluting industrial agriculture system. But bits and pieces have been tried. For example, Fairlie points out that when New Zealand stopped subsidizing beef, the farmers changed from grain fed to grass fed. Feeding cows grain is a terribly wasteful thing to do. Yet one of the first things the new Tory government in Britain did was to authorize an enormous new confined beef feeding operation. So, if you are trying to do grass fed beef in Britain or the US, you have to be able to get a higher price for it. In New Zealand, because the subsidies have been eliminated, you have an economic advantage.
As for things like water management, pest management, soil fertility, etc. Permaculture is designed to be just what it implies: permanent. It is an ecological system as opposed to a ‘poison the symptoms’ system. It begins by increasing biological activity in the soil which increases the carbon in the soil (with or without the help of biochar) which increases the water retention capacity of the soils and the cation exchange capacity which makes soil nutrients more available to plants. Since the plants are healthier, they are better able to fend off disease with their own resources. Furthermore, plants are not grouped into huge blocks suitable for armies of machines and so are less targeted by pests. Since there is an abundance of biological activity, there are many more beneficial creatures eating the bad guys.
Martin Crawford, author of Creating A Forest Garden, has been managing a forest garden in Britain now for a couple of decades. It is generally considered to be the best forest garden in the temperate zones of the world. It can be done. But it is a non-profit–because you can’t compete profitably with subsidized industrial agriculture. Crawford provides, for example, nitrogen requirement tables by plant. Here is the nitrogen budget for a moderate demand planting of 2800 square meters:
Urine (one and half pees per day) 3 kg
Comfrey (4000 cuts) 2kg
N fixing trees in sun (610 sq m) 6.1kg
N fixing shrubs in sun (300 sq m) 3 kg
N fixing shrubs in part shade (400) 2kg
N fixing herb perennials part shade 1kg
Total 17.1 kg of nitrogen
Many of the N fixing plants are, of course, also edible. It is the root nodules that supply the nitrogen.
When I look at the evidence, it is clear to me that a lot of humans can live meaningful lives using ecological science and the pattern language of permaculture. Whether 7 or 9 billion can live meaningful lives with permaculture is a lot less clear. Whether resource wars will wipe us all out is very murky in my crystal ball. But it is clear to me the direction we need to be going–individually and in small groups. It would be nice if the Tories got religion, or if the Democrats and Republicans had an experience on the Road to Damascus, but somehow I think they are all destined for one of Dante’s circles.
The sane course of action for individuals, families and extended families, and small groups will be similar to the path that Peter Bane has laid out for us…Don Stewart
I guess I am somewhat discouraged by my own gardening attempts (even though we are getting a lot of tomatoes and okra and my fig tree looks very healthy). I would have to scale up what I am doing greatly, to feed our family of three. My biggest challenge is watering (we are in a “severe drought”). Without “city water” and watering the plants, the plants wouldn’t do well at all.
The one family I visited who is trying to make a go of it with their own permaculture plot seemed to be having a hard time of it. When I saw it, they were not self-sifficent in food, and made their living selling permaculture designs. Part of the problem is that trees take a long time to get started. Even if at maturity, a given design will theoretically work, the first 10 years can be a problem.
There is no ‘instant recovery’ from degraded soils. The soils around Atlanta were degraded when the first wave of settlers moved on West around the time of the Revolution. They have pretty much been continually abused since then. Sometime you should go down to the ‘grand canyons’ in SW Georgia–they were created by erosion in the years before the New Deal brought some semblance of land conservation.
What is exciting is that we now DO have ways to recover from soil degradation in a reasonable time–at least partially. Take a look at Joel Salatin’s story on the recovery of their family’s worn out tobacco farm. It doesn’t happen in a year, or even two, but it begins to happen when animals are used intelligently. Which we didn’t know how to do until quite recently. Or look at Allan Savory’s fantastic pictures of Africa. You will see that deep soils with lots of carbon really do make a difference in terms of resistance to drought.
And the first step in permaculture is to slow water down and sink it into the ground–not store it in a rainbarrel. The slowing and sinking are usually done by constructing a swale. There are also amazing pictures of the power of swales on the internet, including some from the Dead Sea. Along with swales can come perennials with deep roots.
None of that happens instantly. Peter Bane and his partner have been working on their very plain suburban home in Indiana for six years. But the before and after pictures are phenomenal. From desert to garden.
And some things are gone forever…such as the minerals flushed into the toilets and down the rivers into the oceans. But the loss can be stopped with intelligence.
The Pima Indians ate very well from the desert in Arizona. But there weren’t very many of them. Nobody I know thinks anyone could feed Phoenix with anything like a sustainable system. But there are amazing pictures from Tucson and the desert in northern New Mexico of just what a garden can be created by the simple expedient of sinking rainwater into the ground which is rich with carbon.
I will also observe that one does not create a healthy, biologically active garden overnight. If you are like me, you learn the hard way that maximizing production does not mean maximizing crop area–lots of area needs to be given over to flowering plants which will attract a wide variety of biological life.
If you are gardening, then it is pretty easy to return virtually all the nutrients that you take from the soil back to the soil. And with a little diligence you can hoover up nutrients that your neighbors don’t want such as leaf fall. Which means your garden gets more and more nutrient dense and more and more productive. If you are farming, then you are by definition selling products which go off the farm. Replenishing nutrients is trickier.
How many people can be fed with such practices? Liebig’s law holds here. Whatever is in shortest supply will limit the amount of food which can be delivered to cities. It probably won’t be the raw ability to grow food in the countryside. Transportation, refrigeration, robbery, riots, you name it. For a town dweller, the important thing is to make a plan and get started. Peter Bane and his partner made a plan and six years on, they are in pretty good shape.
Thanks! One of the issues is that we have start where we are, and work from there. That can require a lot of work.
Gail, you show the decline of fossil fuel very sharp at first then slowing down as we approach mid century. I think this is a mistake, the decline will likely be slow at first then speed up as we approach mid century.
There is several reasons that this should be the case. At first all nations will be producing flat out, then as the economic situation gets worse and some nations start to have serious internal problems with their populations, there will be riots and destruction of the infrastructure. There will likely be resource wars between nations and even within nations like Iraq. Also many nations will begin to hoard their resources, keeping it for themselves.
The pattern I am using to decline fossil fuels is equivalent to multiplying by about .96 each year–more or less a 4% decline rate. Over 40 years, it leads to fossil fuels that are 80% as much as those at the beginning.
I agree it isn’t the most reasonable looking pattern. If the issue is a financial crash, I expect that the decline would take place in fits and starts–as a governments of oil exporters are overthrown, for example. Also, resource wars and hoarding as you say.
If everything hangs together, a person would expect more of a convex shape, rather than the concave shape I am showing.
As I read all these comments I mostly see the underlying assumption that somehow we need to keep the existing systems going: heating and cooling and industrial agriculture and high tech medicine and the housing industry and water and sewer systems and so forth.
I suggest that all of you go and live for a week or so where none of these things are available. Life can be pretty good without any of them. There is a lot of work to do–but no jobs paying cash.
If we get back to the fundamentals of what it takes to lead a good life, we find that many of these things are just expensive, non-sustainable distractions. Jesus, among others, managed without them.
As for deaths–nobody ever said that Mother Nature highly values an individual life. Whether of a soil bacterium or a human. Take a nature based look at the situation and enjoy what life has to offer while you can. The ego is an illusion.
That’s true if your society is geared up (or should that be down?) for it, but we who live in a hi-tech, just-in-time world do not have those simple infrastructures to fall back on. In many parts of the world, society hasn’t got past the subsistence farming level, and they still manage to be happy, but we would starve if we were suddenly thrown into that situation by the collapse of fossil-fuel powered agriculture and just-in-time supermarkets.
I have done that Don. The problem is that it requires that you drop the population density by a factor of ten….
Now if I am in the ten percent all well and good, but what about the 90% who have to die?
Leo Smith said:

Minimum, I think renewable energy could give individuals transportation as good as a horse with out the mess in the street.

And on The Oil Drum there is a report about China using coal to feed its chemical industry rather than petroleum as is done in most of the world. Several ‘American’ multinationals are participating in the construction of the plants. Some of the commentators say ‘another defeat for Peak Oil’. Among the products produced in China is synthetic nitrogen fertilizer–which promotes soil degradation while boosting yields in the short term.
My point is simply that Life follows certain rules. If we transgress these rules long enough and far enough, we are going to pay for it with suffering and death. The situation is similar to feeling sorry for the people who buy junk food in gas stations and the middle aisles of grocery stores. Of course Big Food is exercising its demonic powers over relatively helpless and clueless humans…but at the end of the day Life’s rules will be followed. No amount of Obamacare is going to change the outcome–although it WILL contribute to the bankruptcy of the US.
I do not know with certainty what the population density will be when Life gets we humans sorted out. I DO know that a human intensive agriculture can grow a lot more food than industrial agriculture currently does. I DO know that ignorance about the value of horse manure is both endemic and a shameful indictment of our educational system. (John Adams, our second President, investigated the horse manure on London streets with his walking stick and found it ‘inferior to what we make on our farm in Massachusetts’.) I DO know that a sudden collapse of the current system would result in widespread starvation–but I ALSO know that the very reasonable path laid out by Peter Bane in Garden Farming for Town and Country is within the capabilities of most people. The question is mostly: how many people will take heed and actually do something?
As an overall observation, the US is trying to be successful with fewer and fewer people actually producing anything at all that is actually useful. We are at record levels of mental and emotional and physical incompetence and our ‘jobs’ have been skewed toward the unproductive roles of speculation, caretaking for the chronically sick, and the production of junk food. We have mined the Earth rather than husbanded the Earth. While I can empathize with, let’s say, an elderly couple who are in poor health because of a lifetime of bad choices and whose children are all a thousand miles away and who don’t have grandchildren to take care of while the parents work–but that doesn’t mean the US taxpayer can and will support them.
Don, that is all well and good in the USA where actually the countryside could absorb a LOT of the townspeople in a sort of Amish type lifestyle.
In nations in Europe, and say Japan, we depend on a vast excess of energy input to create less than half the food we eat. Take that energy out and we are truly scuppered. The towns and their populations would largely cease to exist. The last time we – the UK – were self sufficient without the use of fossil energy, and depended on renewables, the population was less than a tenth of what it is today, and for most people life was a grindingly poor existence as manual agricultural fieldworkers and the like. Transport was by horse, by horse drawn canal boat, or by sailing ship.
The world has never been renewable. It has never been in equilibrium. It constantly changes to reflect the climate, the chance arrival of new species, the destruction of old all of whom expand to fill the habitats they exploit, then crash back to niches when they exhaust that habitat.
The key is in the term ‘fossil fuel – the remains of long extinct species who created that carbon fuel as waste out of what they found – a carbon dioxide rich, wet, watery world before too may animals had arisen. Its a good thing for us that plants in the carboniferous didn’t worry about making the planet unfit for their children, or they too might have created vast bonfires to burn up their dead and take up the excess oxygen and create more carbon dioxide for themselves!
The Old World and Japan have few options left. On the numbers the only hope is to use nuclear power or suffer massive loss of civilisation and life. And even then the transformation to a low carbon lifestyle will be severe.
That they don’t even realise this at a political level shows the downside to democracy: You can only move as fast as the peoples ideas about the world can and will be changed, and they can be changed as easily for selfish motives as altruistic ones.
And there is no guarantee they will be changed for the better in either case.
The truth is that the political class does not lead, it follows: it is parasitic upon the nation, taking its excess consumption and using it to regulate matters as much to its own advantage as that of the people. That creates a system that is very slow to respond to change. And very disinclined to allow change to happen.
Sometimes that’s a good thing, sometimes its a very bad thing indeed. Wars typically provide the desperation to try the new, as the governments are threatened then with complete destruction of themselves. Lacking wars, we can look forward to at least another decade of weary attempts to keep the ball in the air and kick the old civilisation can down the road. This will postpone but not prevent the final collapse: And make it more sever – as long as reliance is placed on, and resources poured into, existing institutions, they new ones that are more fit for purpose are disadvantaged, and when that becomes understood, there may be few resources left to create them with.
I am certainly no expert on Britain. I do know that some Permaculture type studies (intensively farmed as opposed to industrially farmed) have shown that Britain can feed itself, and even produce a modest amount of animal food. I don’t know about Japan. Recent (last 15 years) studies have shown that Hong Kong and Shanghai have the capability of feeding themselves from the surrounding territories. That, of course, doesn’t mean that either city may not grow to a size which is completely insane or that industrial farming will not be used in such a way that soil fertility is destroyed. It also doesn’t mean that China will stop spending vast sums of money importing US corn (maize) to feed hogs. I wouldn’t claim that the Chinese are any more rational than Americans.
I will also emphasize that nobody I respect is recommending old time farming. To quote from Peter Bane, page 6:
Humans have practiced agriculture for 10,000 years without our understanding why it works, and as a consequence most long-term agricultural practices and the civilizations built on them have collapsed from one or another failure to maintain ecological balance. Again and again, soils became exhausted, salted from irrigation, eroded because of plowing, the climate changed because too many trees had been cut or the population increased beyond the ability of farmers to provide food.
So…as I see it, our charge as humans is to stop doing destructive things and instead partner with Nature to produce the things we need to flourish. And to stop deluding ourselves that we need a bunch of Stuff in order to flourish. How many humans that means for the planet I don’t know. Will a whole lot of clueless people die? I am sure they will. Can I stop it? Not likely. Can I drop a few clues that some smart people will pursue in their own way? I try.
I think you have hit on one of the big issues.
I am afraid that the 90% will go and shoot at the 10% (or 1%) who have set up sustainable living quarters, and take them over.
Scientifically literate people understand that AGW (Anthropogenic Global Warming) is happening to a high degree of certainy. The science, the modelling and the empirical data since the industrial revolution all confirm this.
“The scientific opinion on climate change is that the Earth’s climate system is unequivocally warming, and it is more than 90% certain that humans are causing it through activities that increase concentrations of greenhouse gases in the atmosphere, such as deforestation and burning fossil fuels.” – Wikipedia.
Note that wording of “the Earth’s climate system is unequivocally warming”. That means this part is 100% certain from the data. It is then over 90% certain that this is manmade (anthropogenic).
People who deny or are unduly sceptical about these scientific conclusions are either scientifically illiterate or they have allowed pro-business and pro-fossil fuel propaganda to lead them an illogical and unscientific conclusion. Most climate change sceptics are people who do not understand what science is nor how it works as a discipline.
Nuclear fission power is not a renewable energy source on earth. It relies on finite supplies of fissile materials. Already there are clear signs that peak uranium extraction is approaching.
“The Energy Watch Group has calculated that, even with steep uranium prices, uranium production will have reached its peak by 2035 and that it will only be possible to satisfy the fuel demand of nuclear plants until then.” – Wikipedia.
Ultimately, we have only two choices. Survive on renewables or suffer species extinction. Sooner or later, we will reach the point where only renewable energy and materials are available (all essentially powered by incoming insolation i.e. sunshine.) Thus, those who denigrate the capacity of renewables to power some (probably much lower) level of civilization should give up all hope now. Those who recognise correctly that renewables are our ONLY long term hope ought to keep working for that hope no matter how slim and for how few. Because it is the only hope for a remant of the human race at least while the sun keeps shining.
Other animals just use the energy that comes down from the sun, plus the energy that they get through eating the food. None of this involves what is today referred to as “renewable energy”. Perhaps this is the way all species need to live, if they are to blend in with the rest of nature. If this is the case, it is sort of a big “oops” for humans.
Theses are the people that will survive. Nice video about tribe living in the wood and raising deer. These people live in harmony with nature,

It is beautiful to see these person in action,
I thinks I got it now
Interesting! I agree they can keep on doing this, pretty much indefinitely, unless climate change vastly changes their environment.
I did notice that they were use several metal tools: an ax, a knife for killing the reindeer, and a metal scraper to scrape the deer skin. If these were not available, I presume they could make somewhat acceptable substitutes from sharpened stones or from bones.
Yes. That’s how they used to do it.
You will note that
– they have a monumentality low population density
– they absolutely are NOT vegetarians, and in fact could not be.
It all started going wrong when we learned how to make fire.
I am afraid you are right.
Is there some explanation here for why the global economy would radically drop it’s use of fossil fuels but ramp up it’s use of renewables?
Renewables are currently a “boutique” fuel. They cost more and are more difficult to use than fossil fuels?
If there is a major financial crash and economic contraction …. people would then abandon the cheaper and more convenient energy sources and rush to the more expensive, luxury energy source? This seems like lunacy. If there is a major economic contraction, than fossil fuel use will **grow** as a percentage of the total energy mix, as renewables will decline more than fossil fuels.
It is very hard to imagine a different scenario. A major economic crash such as predicted here is certainly possible, (lots of things are possible) …. but a major economic crash accompanied by a rush to more expensive energy sources strikes me as impossible.
What is actually happening is that everybody is SAYING how wonderful the renewables are, but the reality is that the biggest gains are coming from coal and nuclear in Europe and Asia and gas in the USA.
While Germany rushes to build filthy brown coal plant to replace is politically terminated nuclear.
Given the choice between citizens rioting on account of high fuel prices today, and sticking in a CO2 emitting coal station, that may (or may not) impact climate 20 years down the line, or a nuclear power station that wont, which way do you think governments will go. Are ALREADY going in fact.
The cos/benefit analyses are nowhere near as clear cut on climate change and CO2 as people perceive them to be.
The eco-fringe would have us believe that cO2 is so damaging that it must be prevented at any cost at all. Which is odd, because in thet same breath they reject the most successfully low carbon energy source that is also the cheapest – nuclear. You don#t need a tinfoil hat to realises that at least some of the fuss is not about the planets future, but the future of renewable energy companies..
If you then construct a matrix of climate change possibilities starting with something we all agree – the late 20th century was warmer than the earlier part some interesting options emerge. Especially when its been a great deal warmer and indeed colder in the last 2000 years.
Option 1. The IPCC narrative is substantially correct. Man Made CO2 is raising the planets temperature.
Option 1a. So let it and meet the cost of what we will have to do to deal with it
Option 1b. Build lots of nucelar power stations which are the cheapest and least environmentally impacting way to deal with it
Option 1c Build lots of very expensive renewable energy that locks us in to co-generation with fossil fuels forever. But gives the greens the warm, fuzzies. Most expensive and least effective response.
Option 2. The world is getting dangerously warmer but its nothing whatever to do with CO2.
Option 2a. Carry on building fossil power stains and burning up fossil reserves to meet the changes we can’t stop anyway.
Option 2b. Build lots of nuclear power stations that will be a bit more expensive than the fossil, but will ultimately mean we have more fossils left for longer, cheaper for things we cant plug into the grid, like aeroplanes.
Option 2c build renewable power that isn’t actually needed as CO2 is no longer an issue, and involve ourselves in needless expense.
Option 3. The world is about to enter a rather vicious cooling phase as it has done (at least) twice in the last 2000 years. (some alternative climate scientists draw parallels between the current position of the jet stream, the current sunspot activity and the occurrence of these events historically) Food production in that temperate regions will be badly affected at least until the climate settles enough to work out what to grow, where. We will likley need more energy than ever.
Option 3a. Build conventional fossil plant as fast as we can and hang the CO2 emissions since we will need all the greenhouse gases we can get to stay warm. Assuming CO2 has that effect.
Option 3b Build nuclear as fast as we can – it is going to cost more but maybe the waste hot water can go into greenhouses, which it looks like we might be needing. At least we are protected from massive rises in fossil prices as demand tops out.
Option 3c Build renewable energy that doesn’t free us from dependence on fossil fuels, is more expensive than fossil fuel or nuclear and is solving a non-existent problem we don’t have.
Ok, now in order to agree with the options assumptions, its needful to have done research most people haven’t, which is to accurately use the data from the renewable industry (as opposed to their political lobby groups, whose output is more or less a tissue of lies, when examined in detail) to assign costs in terms of fossil, renewable, and nuclear energy (financial, social and environmental) , and benefits in terms of reduction of carbon emissions, assuming these actually represent a problem.
In the UK two groups of people have done this at least, as have others elsewhere. Their conclusion is that irrespective of whether or not Option1 is the correct analysis of the climate arguments, renewable energy is always the worst possible option to choose for any power strategy.
Mercados (http://www.templar.co.uk/downloads/Powerful_Targets.pdf) has this to say .
“It is often not clear whether the aim of that (having a renewables target, over and above an emissions target, alone) policy is to reduce carbon dioxide emissions, or to deliver renewables for their own sake.”
Professor Hughes of the global climate change foundation, who presents a more complex and in depth analysis of the carbon fuel nuclear and renewables market, is somewhat more pithy.
“The casual assumption that expenditures on green technology represent an efficient and economic use of scarce resources is little more than a convenient fairy tale for troubled times.”
The conclusion that less responsible people than these, like myself can voice clearly, is that renewable energy is in fact not a response to climate change at all, but a response to falling profit margins in the energy generating sector, and that it’s used the climate change agenda to essentially fraudulently hawk their wares on false assumptions and misleading data and a public perception that has been carefully groomed. The use of political lobbying groups that are – in the UK at least – exempt from any requirements to tell the truth, as politics and religion are , are held to be areas which, as they do not directly advertise products from a specific vendor, are “ultra vires” when it comes to the law on providing misleading advertising copy.
This is not to say that in a litigious USA a class action by consumers against such groups, and their commercial sponsors, might not be pursued with some hope of success on the grounds of fraud.
Be that as it may, further analysis of this train of thought brings into sharp focus the actual basis of the IPCC AGW hypothesis itself. We have established motive and opportunity for that to also be misleading and a fraud. As increasing numbers of people here in Europe consider that it may well be. A change mild planetary warming over 40 years is simply ‘normal’ in even historical times, and this one is nothing special at all.
And suddenly an alternative narrative forms. Not of the brave IPCC as a lone voice crying out against a disastrous and certain future, but of a fairly small and not very substantiated theory – one amongst many – that is seen to be exactly the right adjunct to a massive corporate seeking of rent. One that upset the oil majors initially, because it allegedly devalued their resources, but now one they are happy to assist in every way precisely because with careful management of the information flow, the proposed ‘solution’ doesn’t damage sales of hydrocarbon fuels at all. Because the solution actually barely works at all. In fact it increases their value: because it sets the expectation of higher energy prices to ‘save the planet’
And finally, the real competitor, the actual technology that DOES work is demonized completely.
Its a wonderful recipe for profit as long as the truth stays hidden.
Whether or not you believe the received wisdom of the age, or this deeply cynical alternative, depends on whether or not your experience of people in corporations and politics and commerce, marketing and finance has been one of high minded moral altruistic benefactors of mankind or a bunch of greedy lying b***r*ds who would sell their grandmother down the river for short term profit.
Follow the money, see who is funding all this eco-this, climate change that, and renewable other, and you may be surprised.
And Gail, if, having read this extremely long piece of whatever, you feel its has no place in your blog, by all means delete it.
But I felt it should be written. These are not easy times, and when you stumble on what amounts to a multi-billion dollar fraud, you have to say something.
Personally having satisfied myself that renewable energy is verging on, or a clear case of, fraud, I have come to be deeply skeptical of the AGW hypothesis which is its sole justification.
It all smacks too neatly of creating a problem to fit a solution you have.
Leo – you need to master the art of smaller posts.
Certainly renewables could be poised for a big **proportional** growth.
But there are growing from such a small base, they will surely remain a small fraction of the energy pie for decades. (Unless you count hydropower, which the Green movement hates).
My point is this “forecast” is beyond absurd. Fossil fuel use will crash, totally energy use will decline precipitously, and renewables will ramp up quickly? The future, whatever it may be, will not resemble this prediction in the slightest.
Gail should put a clear disclaimer saying this is not a forecast in the slightest, but an intellectual exercise describing what would happen if the world were taken over by Greenpeace.
My point is that renewables are driven by faith and ideology and not by results.
Fossil fuel wont crash, but we will have a decade of energy austerity.
There is presumably an urgent need to change our ideas, but my second point was that all the eco-lobby side produces is ‘qualitative’ solutions. I.e. one man rows across the Atlantic therefore “we will carry on international trade with teams of people rowing ships across the Atlantic” sort of thinking.
Gail is one of the few people – no more than 1-200 – that I am aware of in the future prediction game who actually run the numbers,
In general the world, like the Americans, can always be counted on to do the right thing – after it has exhausted all the other alternatives. I am am juts trying to streamline the process.
Nuclear V fossil is entirely bounded by cost: faced with the one in a million chance of having to evacuate their homes for a year, or the certainty of dying from hypothermia, it is after all a no- brainer. Assuming we still have something resembling a democracy.
Lord knows stoking fuel rods in a big pot of water to make steam to drive a steam engine is a pretty crude thing to do, but its a heck of sight better than windmills and solar panels.
I gave a second reason for looking at this, and I think that is the one that makes sense (but with a different fossil fuels/renewables split). What I said was,” If we encounter a financial crash in the near term, I expect that one result will be at least a 50% reduction in energy consumption by 2050 because of financial and trade difficulties, so this scenario in some ways gives an “upper bound” regarding the outcome of such a financial crash.”
HIgh oil price is nature’s way of brining demand down. The downslope may not be as smooth as I suggested, but the effect will be recession and job layoffs, leading to less oil and other fuel use. It is really this that I am concerned about. (It doesn’t hurt to look at the other scenario as well.)
“HIgh oil price is nature’s way of brining demand down. ”
But isn’t low natural gas price natures way of bringing demand up?
And a high oil to natural gas price ratio natures way of swapping oil for natty gas?
Yes, but it is expensive to pull natural gas out of the ground. Unless the price of natural gas exceeds the price to pull it out of the ground, we won’t get much for very long. There is also a big cost of conversion (including energy cost), and the amount of natural gas available appears to be far too low to substitute for the shortfall in oil supply.
I am not as convinced as you are that nuclear power is safe for the long term, or I might feel as you do. We don’t have the facilities to reprocess all of the left over uranium, and we don’t have the nuclear plants that would use the plutonium in it either.
The climate change situation is more complex. The climate has been changing for a long time, and humans have been causing climate change since we first started burning down forests when we were still hunter gatherers. CO2 pollution is a problem in and of itself, apart from climate change. But like you, I don’t see “renewables” as a solution. They don’t do enough and they are more expensive than we can afford. There are all kinds of indirect effects that people don’t consider, as well, that make the direct savings calculations invalid. For example, if renewables ramp up energy costs in some parts of the world, the higher costs will tend to increase imports from parts of the use world that use coal as an electricity source, and indirectly raise CO2 emissions. (We have been seeing this in recent years. Carbon taxes seem to have the same effect.) See Is it really possible to decouple GDP growth from energy growth? and Thoughts on why energy use and CO2 emissions are rising as fast as GDP.
I think that the push toward renewables has several sources (besides climate change):
1. Desire to help the local economy with a new local business. Corn ethanol arose from a need for a new market for corn. Renewables sound more local than oil imports, especially if it is possible to ramp up local production of wind turbines or solar panels.
2. Fear of peak oil. No one can talk about peak oil, so climate change is a convenient proxy–at least, theoretically, more distant in its impact.
3. Desire for politicians to look like they are doing something, if oil and other energy prices are rising.
4. There is a myth that renewables will at some point become less expensive than fossil fuels, and at that point, demand for them will take off. There are too many fossil fuel inputs for this to be true. Also, no one stopped to think that perhaps the economy can’t really function on high priced energy, regardless of whether this energy comes from fossil fuel or “renewables”.
5. Misunderstanding that renewables really are “renewable”. This is largely the choice of a clever name for them. They could best be described as “fossil fuel extenders”. If we lose fossil fuels, we lose renewables, because they are so dependent on fossil fuels (for example, for maintaining the electric grid, and for building new cars that use biofuels).
6. Need to reduce oil imports. The countries most interested in both carbon taxes and renewables are ones that cannot afford oil imports, so anything that might possibly help them is important. (Of course, if world oil production is maxed out, its production is likely to remain the same, whether or not the country in question reduces its consumption.)
7. Academia tends to go along with “fad de jour”. If funding is for research on renewables, that is where the research will be.
“Leo, I am not as convinced as you are that nuclear power is safe for the long term, or I might feel as you do.”
Gail: that is the sole difference in our positions.
I am not a nuclear engineer – I am a simple electrical engineer, but I have made it my business to asses where nuclear stands from that engineering perspective. In essence there are no issues with it that cannot be solved at far lower cost than e.g. ‘renewables’ whose issues are intrinsic – not to the technology, but to the energy source itself.
There is a circle of self fulfilling prophecy about the way nuclear is demonised, so that no one is willing to tackle the issue for fear of a political backlash, which means that the issues don’t get tackled, and so the perception is that the issues cant be tackled at all.
Likewise, in that climate of fear, extremely conservative standards based on the LNT* model of radiological risk were developed. Short of subjecting people to years of low level radiation and seeing how many did die, that was a reasonable approach, but once again that model – though absolutely flawed – has been held as evidence that:
‘Even the government says there is no safe level of radiation!’.
Radiation is complex. And the damage it causes even more so. Not only is the type of decay (alpha, beta or gamma) relevant, so also is what the decay product is, and how biologically active it is. Radioactive iodine is possibly the worst of all: it concentrates in the thyroid where it can do great damage. Fortunately it’s more or less gone in a few weeks, as its high radioactivity count means it transmutes fast.
By far and away the greatest radiation killer is sunlight: high energy gamma rays (UV) from the great nuclear reactor in the sky, (the one that drives all that ‘renewable’ energy) cause more deaths from cancer than anything else by a large margin. In the UK its comparable with deaths from road traffic accidents.
The second biggest killer, is radon, that occurs naturally in many places: by itself it represents a slight risk, but that risk is massively magnified by smoking or anything that impairs the lungs ability to clean itself. Radon decays via alpha and beta emissions through various isotopes of polonium, bismuth and lead, all of which are poisonous and many of which are carcinogenic. Inability to cough that sort of stuff out leaves the potential of particles of them in the lungs to cause real damage. Fortunately radon is not something the nuclear power industry produces. It’s entirely natural.
And its not the only entirely natural radioactive compound. Background radiation from entirely natural causes like cosmic rays hitting the earth, is responsible for nearly all the radiation we are exposed to – apart of course from the sun which bombards us with gamma rays. Carbon 14, potassium 40..these are in the air we breathe and in the food we eat. As is radon. In fact the total radioactivity of all of these is 4 times greater than anything man made, and that is from MEDICAL use of X rays and radio isotopes. Next on the lists is the residue of weapons testing in the 50s and 60s, at a teeny fraction of the total, and right at the bottom, contributing 0.5% or less is the residue of making electricity. Including Chernobyl and Fukushima..
So there really IS no problem of radiation at all. The problem lies in the fact that whilst people are prepared to risk death by lying on a beach, and want their X rays and their cat scans and their transcontinental flights – all of which expose them to far more radiation than any remote nuclear accident conceivably could – they have been educated to fear any radiation that’s not natural or medical as if it were somehow worse…
And that drives up the cost of nuclear forcing it to maintain huge insurance against totally unrealistic scenarios, and has paralysed the treatment of waste. Which is all grist to the mills of those to whom the greatest threat is nuclear – not because it kills people, but because it is a well proven reliable energy generating technology that actually competes well with coal and gas for base-load generation, but they want to sell something that doesn’t.
IN short the cheapest way to decommission a reactor is to wait 5 years, fill it with concrete and cover it with trash and a layer of soil. Which would actually work extremely well. HOWEVER one is required to spend billions on studies that will demonstrate that in 10,000 years time one atom of plutonium won’t somehow get out into an underground stream. Or something equally irrelevant. And of course that can’t be done. So by setting impossible targets nuclear can be discredited, or made impossibly expensive.
Likewise spent fuel could be ground up with general hardcore and dumped in a hole in the ground and would be no more radioactive overall than the actual ore from which the uranium was originally extracted.
But by the magic of ‘unnatural’ intervention, anything that has been through the nuclear industry, power or medical, suddenly acquires a big warning sticker and becomes qualitatively different, it seems.
Leading to some curious and interesting anomalies.
1/. Coal ash (fly ash) is very slightly radioactive due to concentrating the minute amounts of uranium that generally coexist with coal. If the coal had been through a nuclear facility, it would be classed as ‘low level waste’ and be disposed of by burying in sealed containers. However if it’s just ‘coal ash’ its perfectly all right to combine it with cement and make ‘cinder blocks’ for use in the construction of domestic homes.
2/. In the UK we have two areas where the normal natural background radiation is so high (Dartmoor in the South-West, and parts of Aberdeen in Scotland) that no nuclear power station could ever be built there, since the dose received from entirely natural causes exceeds the total permitted annual dose for nuclear power workers. People have lived there for centuries, and there is a just detectable increase in lung cancer amongst smokers who live there, and almost no detectable increase in non smokers. (compared with the general UK statistic for these types of people).
3/. Post Fukushima, some diplomats were sent home amidst concern that the background radiation levels had risen slightly in Tokyo. Sent home to cities that had considerably higher background radiation than Tokyo ever reached…Japan is a very low radiation country, having little coal or granite it seems.
What can you say? nuclear power is about 100 times safer than the regulators regulate it to be, and about 10,000 times safer than its painted by some. That’s the factual basis. Nothing can’t be done to fix safety and waste disposal to reasonable standards, but of course the game is to insist on totally *unreasonable* standards.
Politically of course, no one got elected advocating nuclear power, so its likely that no one will resort to it once they have bankrupted themselves on getting rid of it and putting in coal, gas or renewable energy.
It is however under great expansion in ex soviet countries, India, China countries of the middle East..the only nations reducing it are the USA, Western Europe and .parts of the British ex commonwealth.
IF we reach a fossil peak though, and we need quantities of primary energy, its the only card left in the deck. The issues of ‘renewables’ cannot be ‘solved’ because they are issues with the energy sources themselves, not the technology that collects them.
No one wants nuclear out of some fascination with atomic technology: rather we need nuclear technology because we have run out of alternatives. That is the quandary the Japanese face. They are scared of it, they don’t trust their politicians or their engineering companies, yet realistically they cannot do with out it.
As I said earlier, the pressure is off the USA for a decade or so if the unconventional oil provides a short term stopgap, but for some of us that option is already running out. Or being stifled by more opposition from the eco-lobbies.
If its a choice between nuclear and nothing, I know where my money is.
(there is an excellent book called ‘radiation and reason’ by Wade Allison, that puts the whole issue into perspective, and is recommended for people who actually want to know the facts.)
*Linear No Threshold, based on the assumption that if exposure to radiation of value Y causes 50% of people to die (data from say Hiroshima), than exposure to 1% of that value will cause 0.5% of people to die etc etc. It was introduced as a worst case scenario, and its absolutely been shown to be far to conservative – up to 100 times too conservative in fact. Chernobyl had the anti-nuclear brigade using it to predict hundreds of thousands of deaths, The official WHO figure is I think just 78 people and about 3000 incidences of (non lethal) thyroid cancer which should have been prevented by iodine pills if the state there had been as fast as the Japanese were. So low has been the death toll that millions of people are now convinced its all a government cover up, as if 200 thousand people dying of cancer could be covered up..
I know I have heard quite a few of those comments before, and it is quite possible that your comments are right. There was a great deal of argument as to wether Chernobyl did or did not cause adverse health effects. Fukushima is the new test case. I know that there has been discussion recently of the thyroid nodules found in Fukushima children.
I am sure there must be information about the long term effects of the atomic bombs in Hiroshima and Nagasaki.The Wikipedia article (in the section Post-Attack casualties) talks about one study claiming there were 200 excess leukemia deaths and 1700 solid cancers–not a whole lot. Another seems to study suggests more.
Even if you are right, if people don’t believe that it is not a huge hazard, that in itself is a problem.
If nuclear is not a huge hazard, it would seem like some of the costs of nuclear would be redundant as well.
(By the way, I don’t have granite countertops in my kitchen or granite as flooring. I’m not sure I would want them in the first place, but I was aware of the radiation issue as well. I probably make up for my lesser radiation from countertops with my airline flights, though.)
I should perhaps have made myself more clear. If there is a financial crash, there might be a 50% drop in fuel use, but it would be the most expensive 50% that is likely to go. So I would expect renewables to stop ramping up. The drop in fossil fuels might be less than the 80% that I postulated in the renewable fuel ramp-up scenario. If coal is the cheapest fossil fuel, and can at times be mined with little complexity, it might continue to the largest extent.
So this is chart you call a prediction …. is in no way an actual prediction.
Thanks for clearing that up.
Right now one of the topics I am looking at is the example of Edo Japan (1603-1867) as a possible model for what our future might look like. During that era Japan was isolated from the rest of the world, under feudal rule, and powered by current solar energy (last 2 or 3 years). Some relevant links from Energybulletin.net: http://www.energybulletin.net/node/5140 and http://www.japanfs.org/en/pages/022419.html
I am also reading a book on Edo Japan entitled Just Enough by Azby Brown (2009)
Obviously, it was a society that was living very close to the margins materially while having a cultured and literate populous. Direct sunlight was used in every conceivable way, and everything was treated as a valuable resource that was used and recycled numerous times. Edo (later Tokyo) had a population of 1.2 million and 4000 used clothing stores.
No doubt getting there would be wrenching as a country re-set to a new balance between land, people and resources. At the same time, the fact that such a society existed is encouraging in contrast to all the talk of total collapse.
Japan only had 30 million people back then, and now it has about 127 million. There were a lot more large fish in the sea, back then.
There is certainly more that can be done in the fashion it was done earlier, but it makes it much harder with a much larger population.
I have been following your posts recently with interests as they follow my thoughts. I guess you develop in a very logical direction and this stimulates readers thoughts in the same direction. We see now that banking has peaked as is usual before a big crash like in the 30s in % of economic activity. If finacncial industry is strongly reduced in total due to less opportunity and regulation and firings of employees and less young people will seek a job there then the problem with growth coupled to finance, bank interest and corporate dividends will be less important. The financial markets are being starved and are starving the small and medium businesses of funds which businessses make the creative life changes in the economy. The powering down of the economy back to horse buggy tech will become a real opportunity for millions of citizens locally along with fresh garden produce to market and candle manufacture and wicker furniture and baskets a la 1970s hippies once the brownouts and blackouts get more common and international fruit delivery (kiwis, bananas) in cooled containers is reduced. The big banks will probably die and coops will take their place with the local scripts. A reduced GDP is no problem when you consider that unemployed women at home and men in the garden eat and make clothes without any statistical plus for megacorp, wall street, TBTF banks. TV and internet is just such a waste of time and computerization in workplace (enter data several times for insurnace and govt. records, etc.) wastes so much worktime for all concerned (police, hospitals, educational) that loss of these tools would be positive net benefit socially and save massive amounts of energy. Same with packaging. Just take away the plastic in medicine(rewash glass needle and shopping and carry it home in your own bag. So a reduction in per capita energy consumption means an increased qualtiy of life most certainly. I would imagine a 90% or more reduction in GDP(and energy usage) per capita would be no problem. The problem is the 10% we actually need and maintaining actual levels needed for survival, like a minimum caloric intake until we get back to a sustainable population level at a lower level of consumption globally (with corresponding die off here and there due to ethiopia type conditions or syria type civil wars). Less involvement by big powers and their megacorps and banks and militaries would allow local development of culture within countries (no Walmarts in China, Mexico, Egypt and local stores and production in USA and Europe instead of pure Chinese throwaway manufacture for everyone) which would be for local conditions more useful everywhere. Generally if USA/Europe/Japan use more energy than they consume they have a long slide down austerity’s slope as we see in Spain and Greece, in the localities in Southern Europe and US going broke. The social welfare state was a pipe dream to maintain social peace and prevent warfare in a temporary high energy industrial society. On the downslope food rationing cards(food stamps for everyone?) and war time gardening could do the trick but much earlier deaths due to lack of high tech medicine will probably balance out lots of financial problems(state pensions and medicaid, etc.).
If major systems “stick together” what you describe might work.
But if food production is not enough outside of big cities, and cities can’t produce for themselves, that could be a problem. Intermittent power could cause problems with water /sewer, leading to disease, particularly in densely populated areas.
There are also questions of unforeseen circumstances like government overthrows, and countries breaking up in to smaller pieces. They could be a problem for commerce.
“If we encounter a financial crash in the near term, I expect that one result will be at least a 50% reduction in energy consumption by 2050 because of financial and trade difficulties, ”
With re: to Figure 1 – weren’t there at least a half dozen significant financial crashes during the 1820 – 2010 time frame ….
and yet the graph still grows.
I think to create a 50% reduction in total energy consumption would require something much more significant than a crash. Perhaps a giant meteor is what you’re anticipating?
We haven’t had a major credit implosion of the type I am expecting, that will affect the whole world. We have had downturns in one part of the world or another, and debt defaults. But the rest of the world continued on, and was able to pick up the pieces.
Even if the crash were of “only” the US and Europe, and the rest of the world refused to pick up the pieces, it could be a major problem. Eventually the others would fall as well.
There have been multiple global financial crashes during the 1820-2010 timespan. The economy has been globalised for some time.
The Great Depression is the most obvious example, but there were global panics and economic contractions throughout the 19th century.
And of course, the most recent global meltdown … from which Global GDP took all of 20 months to recover.
I thought the focus here was energy limitations? Predicting a massive crash in the next 12 months ….. this will reflect very poorly on this blog if. 12 months from now, the Global GDP merely muddles along with “lower than forecasted” growth.
You call this recovery after 20 months? I think it is mostly papered over with more debt.
You do not believe the Global GDP numbers or the global energy numbers? If you do not believe these numbers why make charts with them.
The global economy was very indebted after World War II. By almost any reckoning, more indebted than today. Perhaps there is a history class at your local community college that can help you with this.
I’m surprised by your comment. You have spent the last year correlating GDP and oil useage. Which would means the world has recovered. I would say United States has recovered also without the false real estate demand of easy money. The US papered over debt is the penalty or real cost for past “bad” policy. If “recovery” means going back to 2006, than god help us all.
If “recovery” means going back to expecting a better future, than smart good investments from the private and public sector are required. War is not a good investment for the total sum of the population, but can be profitable for a small portion. Today in America, politics (to agree on the way forward) is our biggest problem holding back a bright economic future for the whole, not a future shortage of energy.

All nuclear power is also very fossil fuel dependent, and complex. I doubt that nuclear power will survive the end of cheap fossil fuels. If we de-complexify our societies, either by choice or not, nuclear power will not only cease to be a power source, it will be a liability to those living around them, including all those farming what’s left of that thinning topsoil that rests upon the vanishing Ogallala Aquifer. Not a pretty picture for the future.
Nuclear power in the final analysis does not require fossil fuel. As I pointed out given enough NUCLEAR power you can synthesise any hydrocarbons you need.
Nuclear power hardly adds to the background radiation of the world overall by more than a fraction of a percent or so. And really the unpleasant stuff can be stabilised and buried deep, or ‘burnt’ in other power stations.
All the ‘problems’ of nuclear power are soluble at far less expense than ‘renewable’ energy whose fundamental problems are completely INsoluble, because they are not problems with the technology, but with the power source itself.
I am afraid you are correct.
I think the essential thing we have to hope for is that most of the developing world can develop their economy and grow with renewable energy sources as main input. If they could mostly skip our stage of total dependence on fossil fuels. This would already work for a big part for electricity supply. Transport is still a major problem when it comes to that. Although maybe local transport in cities could be electrified more easily, especially if people don’t feel they need to drive at high speed.
I am afraid I am not very convinced that renewable energy will get us very far. Maybe some hydroelectric, but that isn’t enough to spread among all of the people today. So-called renewable energy is so fossil fuel dependent, that it gets very discouraging looking at it.
Minimum, I think renewable energy could give individuals transportation as good as a horse with out the mess in the street. World War I was fought with horses.
So does that fall under the definition of economic collapse?
I don’t think I understand what you are saying. Renewable energy doesn’t give trains or trolley cars. Fossil fuels do. Renewable energy gives us intermittent electricity, and it gives us biofuels as it uses up pour soils.
Horses at least are renewable, even though they create messes.
Well don’t feel bad, I don’t understand what I write half the time either.
My point of the comment was at minimum with today’s technology we could supply our transportation needs without financial or economic collapse. Yes, we would have to change our expectations and how we manage our resources, but it doesn’t have to mean the end of the world or kaos.
A small electric bike using a KWH per day could match the primary individual transportation vehicle (the horse) of 100 years ago.
Now living in Atlanta without AC. That’s going to mean some kind of collapse.
I think that what Gail is saying is that stuff is already collapsing, not because we have run out of oil, but because we have run out of cheap oil.
Collapse is a relative term anyway.
What I suppose we are most concerned with is a positive feedback loop that some collapse causes more collapse and so on. That for example, a week without food causes riots, wholesale destruction of property, stores close and people who can move out…and you end up with a lot of people essentially dying in some enclave.
“UN food drop into Detroit refugee camp” headlines..
“Collapse is a relative term anyway”. Exactly, something we can agree on. I would like to add to that, “Nothing lasts forever”.
At this time in the world, I don’t see stuff already collapsing. It was a Friday night in June of 1974. Fresh out of high school and we hadn’t seen lines at the gas station for months. The price of gas had almost doubled from 33 to 60 cents, lots of people where selling their big cars for small ones. I said to my best friend, let’s go do something. He replied “Let’s go drive around, because petty soon we may not be able to do that anymore”. For whatever reason, I remember that comment as if it happened yesterday. Well, 38 years later things haven’t changed that much and I’m still driving around.
I would like to add one other thought of the day. Those insurance actuaries only give me a 10 to 15 percent chances to make it to 2050 and it’s a nice summer day here. I’m going to drive (actually ride my bike) to the beach.
Change can be good thing
I think there is a relative kind of collapse taking place. Kids out of college are having a much harder time getting “good” jobs. Instead of working on building new highways or new railroads or new electric lines, we are having a hard time keeping up what we have. Real wages aren’t rising by much. Airplanes aren’t any faster than they were years ago (or cars or boats). Quite a bit of our innovation is focused on using less oil/ energy.
David Korowicz has written a very good article on systemic collapse, “Trade Off: Financial system supply-chain cross contagion – a study in global systemic collapse ” with a lot of system dynamics jargon in it, which bears careful reading.
http://www.feasta.org/wp-content/uploads/2012/06/Trade-Off1.pdf [1 MB]
… collapse happens when a system crosses a tipping point and is driven by negative feedbacks into a new and structurally and qualitatively different state, one with a different arrangement between parts and a fall in complexity. The operational fabric could cease to operate and the systems that are adaptive to maintaining our welfare could cease or be severely degraded. As a society, we would have to do other things in other ways to establish our welfare. Functions and specialities, a diversity of goods and services, and complex interdependencies would be lost.
The speed of collapse would be set by the speed of the fastest and most responsive systems
coming out of their equilibrium, causing cascading failure across other systems. In
particular we will consider that the monetary and financial keystone hub would spread
contagion to the keystone hub of production flows, which would feed back into the
financial and monetary system and other keystone hubs. The speed of contagion would be
set by the operational speeds of these hubs. As the operational speeds have increased along
with the growth of the globalised economy, and the functioning of more complex societies
have become evermore dependent upon their moment-by-moment, day-by-day operation,
the potential speed of collapse has risen.
We are not in ” a new and structurally and qualitatively different state” yet, so the usual rules are still holding, but we can sense the tipping point is near.
Thanks! That is a very good quote.
I think these words fit here:
“You really need a cheap oil economy to support an expensive oil economy. Without that underlying cheap oil economy, we’re probably not going to get much of that expensive oil that’s in difficult to get places, or that requires some extreme and complex production method for getting it out of the ground.”
James Howard Kunstler
AND IN LESS WORDS:
“Unconventional fossil fuels are caught in a paradox – that their EROEI is too low for them to sustain a society complex enough to produced them.”
Those are good ways of putting the problem. We have reached the edge in this regard. What we get is likely to be a steep drop, not a nice downslope as in the Hubbert Curve.
Gail: Is a state of “permanent recession” even possible? Or must the feedbacks from that demand destruction result in a catastrophic collapse, and in short order?
well all is POSSIBLE but I have to say that my personal feeling is that a flat GDP as we transfer to a ‘new’ economy is a very fragile tightrope to walk.
But with care a relatively stagnant outlook might be possible. It has historical precedent.
The basic assumption behind a purely capitalist system is exponential growth. 0% just isn’t compatible with capitalism.
I think that is nonsense actually.
Capital is always required to replace ageing infrastructure, even in a more or less stic economy.
Perhaps you mean debt financing by fractional banking rather than capitalism…that is definitely highly indadvisable in a zero growth economy..
I am afraid that a permanent recession is not really possible, because of the tie-ins with the financial system. The problem we have is that the huge system of businesses and governments worldwide that we have built up depends on the financial system as we know it, and it depends on having fairly cheap energy.
The issue I see is that we always build up from what is in place today. For example, if there are two drugstores nearby, and you are looking to place another drugstore, you will probably place it elsewhere. There are millions of little decisions of this sort made when adding new businesses, and when old businesses are removed.
I am afraid that a collapse of the financial system will make a lot of businesses not viable–especially if it turns out that they have no way to pay their employees. Hopefully it wouldn’t be that bad, but if the electricity in a city goes out for good, it seems like the banks in town would have a hard time accessing records.
Years ago, many businesses were run without electricity, without cars, and without many things we consider necessities today. There were manufacturers to support them–including buggy whip manufacturers. But at this point, it would be very difficult to “go back” because it would be hard to build up the proper network of businesses plus many other things that supported it–education, cultural practices, buildings with windows that open, etc.
Its rather worse than that Gail. We could not support the existing population densities without the energy. Losing customer records in banks is not a big deal. Losing the food and water and the sewage pumps is a far more dangerous scenario: the accepted time to live of a city without these things is about 6-8 weeks before a majority of the population are dead. Not unable to access their ATMs. Dead.
Pre industrialisation the average UK distance to a market town was about 5 miles. Any more than that and the food would be spoilt before it got there, and the horse would have eaten most of it to get there. Livestock could be driven – you had the cowboy drive, we had geese..Norfolk geese were WALKED to London..
But the UK population was a tenth of what it is today..
And that is essentially where those that fail to bother to do the sums on energy are wittingly or unwittingly taking us. Towards 90% or more population collapse and the end of cities as we know them.
How’s Detroit these days?
I agree that we could not support existing population densities without energy. Jared Diamond in Guns, Germs and Steel talks about cities having to keep importing new members (I forget in which century–not terribly long ago), because of the problem with infectious disease.
Unless we have water and sewer systems working, we would have a hard time living in cities. The reason I mentioned electricity is because it seems to be tied in to all of these systems.
You are right about food and water and sewerage, but money is vital too, since it is built into the way we do things.
I live at Mission Beach in tropical north Australia, and we have been hit by two Category 5 cyclones in the last six years. Since the power was off, the banks couldn’t open and ATMs and EFTPOS didn’t work. Despite the stories of the community “pulling together”, it was not like that amongst the business people. No one was extending credit to locals, so if you didn’t have cash, they refused to serve you. Very quickly all the cash was gone and the shops had to close because they had no paying customers.
We recovered only with the assistance of “the outside world”. Now imagine if the whole region was without power – a deadly embrace of problems. Even if you could contact a supplier for that vital part (a petrol generator’s capacitor in my case), you couldn’t pay for it, and you couldn’t buy petrol to go and collect yourself.
That is a good example, thanks!
“Can We Really Hold On to the Industrial Age, with Virtually No Fossil Fuel Use?”
Not the one we have now, no, but we can certainly build a slightly different one.
I will make the points for brevity as bald assertions with no supporting rationale.
1/. Since INTERMITTENT renewable energy REQUIRES both massive installations and co-operation with a stored fuel source for reliable dispatchable delivery, renewable energy of the intermittent sort is a total blind alley and will never produce more than a (small) fraction of current needs. In short, it’s a bolt on fuel-saver for fossils. Not an energy source that can operate in its own right.
2/. For all applications where hydrocarbons are the materials of choice they can be synthesised. So provided there is access to relatively cheap energy, other uses of hydrocarbons beyond energy production can be covered by synthetic plastics and oils etc. I don’t have US figures but in the UK less than 1% of the oil ends up as chemical feedstock. Its all being burnt for energy.
3/. Therefore most of what we need to do can be done if we can find a stable source of relatively cheap energy that relies on releasing stored energy (like fossil fuel) , rather than capturing transient energy, on a ‘use it or lose it’, basis (like most renewable energy).
4/. The scale and efficiency of bio-fuels as well as the competition with food production more or less rules them out as well.
5/. That leaves a massive shortfall that can only be covered by one technology that we actually have in production, which is nuclear fission. Not what anyone wants, but what everyone (once they have analysed the real issues) will need…
6/. Since saving uranium is not really an issue, and nuclear power is not suitable for fast dispatch, and is always cheaper than ‘renewables’ there is no point on co-operating ‘renewables’ with nuclear.
7/. Therefore we will see over the next 50 years (or others will) either complete collapse and depopulation of post industrial societies, or a shift towards nuclear energy for primary energy production as fossil fuel becomes too valuable to burn, and more expensive than nuclear power. Those things that can be adapted to use electrical power (railways, ships) will see a resurgence: Those that essentially cannot (long range cars,trucks, aircraft) will suffer a near terminal decline.
8/. This will put a lot of pressure on primary resource production – mining, forestry, agriculture, as much of this relies on fossil powered ‘portable power’.
9/. The conclusion is that new ways of doing things will emerge. The important thing right now is to do the necessary calculations that confirm that renewable energy, no matter how emotionally attractive, is not a realistic solution, and avoid wasting time money and energy on it. As David Mackay says “I love the idea of renewable energy, but I love mathematics as well”. To which one could also add ‘We don’t love the idea of nuclear power, but we don’t love the idea of no power at all, even more”. In this context I would estimate the USA to be 3-6 years behind the curve – Europe is already being forced to abandon renewable energy on cost and popularity grounds. Whilst the USA has more fossil resource, and more nuclear and hydroelectric power, so has not actually had to face up to the reality of actually building a ‘renewable’ grid that works at sane cost.
If we could find a safer way to do nuclear–say with thorium instead of uranium–I would be all for it. I agree, it is hard to look at the numbers for renewable energy and be very enthusiastic about it.
The problem we have now is that we have a large number of old nuclear power plants. I am not sure that we have the funds to decommission the ones we have, or a way to store the spent fuel. Depending on electricity to power cooling pools for years seems iffy as well, after the experience in Japan.
With all of the problems with the aging old nuclear power plants, it is not clear where we will find the funds to build a number of new nuclear power plants. Most of the inputs for building new nuclear power plants are fossil fuel based as well. With governments getting poorer and poorer, I don’t know who is going to backstop the costs involved.
Really the numbers are not an issue if you take a sane approach. Of course the vieww promulgated by those who stand to lose the most from a nuclear renaissance are not sane. Or not honest. Whatever.
Frankly you could just take an old cold war ‘plutonium boiler’, fill it with concrete and heap 50ft of soil on it and leave it a few thousand years for people to wonder about what the ‘nuclear age barrows’ were, whether they were monuments of some kind of religion.. 😉
As far as spent fuel goes Gail, if the pond is big enough its doesn’t need to be pumped. TEPCO have been roundly criticised – and rightly so – for overfilling the used fuel pools so that they did require pumping. The decay heat is essentially gone after about 2-5 years anyway. Its not really that long. After that is simply a matter of shielding
BUT they did that because of the intense political opposition to fuel recycling and reprocessing – because what comes out the end is weapons grade plutonium as well as new fuel. Its expensive to do it – its cheaper to use new uranium – and the reactors to burn plutonium need to be specially adapted.
In some ways that was a problem of politics. The political opposition to nuclear power and et social need FOR it combined to produce a result that benefited no one.
If you take a step back from the emotional narratives, you come to the final conclusions that
– there is no real alternative to nuclear power and
– done properly it is cheaper than the other non fossil alternatives, and safer.
– you don’t store used fuel: You reprocess it into new fuels. (Using a ‘uranium tax’ to fund it.
Nuclear power is cheaper than renewable plant. The general figure is something like $5bn per installed GWe including decommissioning. Over a 40-60 years lifespan that leads to – with reasonable ROI – per unit electricity costs not much greater than coal or gas and considerably less than renewables plus gas backup.
In the case of the UK the £60bn of taxpayer money that went directly to prop up failed banks could have taken us to the sort of 80% nuclear electric generation that exists in France. £10bn has been spent on wind so far for an average 3% grid contribution.
To create an all nuclear grid would take around £150bn. The governments proposals for CfD forward selling of fossil free electricity provide a stable environment in which prices and profits are constrained within limits just high enough to encourage private investment. A 40 year bond paying 7.5% or so to fund nuclear power with a triple A rating is the sort of deal its hard to find these days.
The problem is not finding the government money – because these are funded privately. The problem is creating the regulatory and political environment in which the risk of e.g.a Merkel simply pulling the rug from and entire industry with no compensation, is eliminated.
All these issues are soluble. Renewable issues are simply not soluble. Not on et scale needed.
And the greatest resurgence in nuclear is coming from those places that know it, the oil states that are running out of oil, and the emerging nations that don’t have any.
In the US, companies wanting loans for Nuclear Power plants need government backing for the loans. Too many problems with cost overruns and nuclear power plants never being completed, I think.
well that is sortable by better contracts:-)
The UK is pioneering a ‘financial instrument instead of direct subsidy’ which means that the consumer rather than the taxpayer underwrites the project, but they are a counterparty as well, so they get any upside of the risk.
If you like the government arranges to arbitrate a contract between the consumer and the power generators to buy zero carbon electricity on a forward contract at a fixed price.
If the market price of electricity is below that (strike price) , the consumer loses out. If its above, they get the electricity cheaper than market price.
Then its up to the commercial entities building the stations to asses their own risk.
The idea is to raise the strike price until the plant gets built 🙂
The money doesn’t go on the government books so it technically isn’t a subsidy.
The intermittency problem with solar and wind is being addressed by providing large banks of capacitors to store energy, which is released as needed on demand. Ultra capacitors which can store and release energy even at extreme temperatures are in the works as I write (batteries have severe problems when temperatures are extreme, but ultra capacitors do not).
I see you are not an engineer, or a mathematician 🙂
I hope you are also not an investor.
High temperature solar thermal can easily and cheaply avoid the problem of intermittent production with sensible heat storage. The larger the storage system, the more efficient it becomes (due to scaling advantages of the ratio between surface area and volume), so it is possible to construct multi-week storage systems out of giant insulated piles of crushed rock, using air as the primary heat transfer fluid. The current trend toward molten salt storage allows multi-hour storage, but will never be cheap enough for solar thermal to achieve base-load reliability.
Unfortunately, even though solar thermal is technically feasible as the world’s primary energy supply (as is nuclear), it is too late to make the huge investments required for either solar or nuclear to substitute for fossil fuels. Even the gradual continuous economic recession outlined by Gail, much less economic collapse, will prevent these investments from being made.
It’s worth pointing out that a larger heat storage capacity implies a lower real-time electrical output, as more heat has to be diverted to storage, the pay-off being the ability to withstand longer periods of unhelpful weather.
The much-touted Gemasolar plant at Seville, Spain, that produced electricity for 24 hours on July 4th last year, had been storing heat in excellent conditions in summer for 5 days previously. It proved the point that 24-hour operation is possible, but it also underlined the point that it couldn’t do it every day in summer, and not at all in winter, when the insolation only have been about half as much, and less if it was cloudy for a week.
For a plant to be able to produce a reliable 90% of capacity 24 hours a day all year round, its heat storage would have to be gigantic and its rated electrical capacity quite modest. It would then seem to be very expensive per MW.hour .
It is also worth noting that Gemasolar has only 20 MW capacity, which is only a pin-prick, and that it is Spain, where lavish government support was available, but probably is no longer.
I see you still have no idea of the actual constraints on storing energy in a heat bank, the scale. the efficiency, or the cost.
There is a cost involved in all of this that people did not build into their feasibility estimates.
Like the cost of developing science fiction products in a world governed as far as we know by inflexible laws of nature?
Not to mention the sheer insanity of storing massive amounts of energy in a capacitor
And hoping that one day it wont develop a fault that results in a medium sized atomic-level explosion.
Hmmm..as you said in the title, “Optimistic”….
I’d prefer to match the energy forecast from 1820 to the ecological forecast from 1847. That’s when the US reached Peak Soil, and it’s been down hill ever since, but propped up by such things as ‘the green revolution’. the ramp out over the cliff with this will be startling to witness as the collapse rips apart that ramp and leaves the vast majority out there doing a Wylie Coyote running in mid air:
1. topsoil in the main US agricultural belt is down form feet to 8-10 inches. At 6 inches pack up and go home ’cause it’s not enough for root structures in the plants we’ve come to depend on.
2. the great Ogalala aquifer under 174,000 square miles of that agricultural land, is almost done too…
We’re now into The 6th Mass Extinction at a rate never seen before in the geological records, and much less people are aware of this than peak oil….best go read “Overshoot” by William Catton, or at least the definitions page at http://greatchange.org/footnotes-overshoot.html
“exciting times” huh?
I am afraid we live in way too exciting times.
I read David Montgomery’s book “Dirt: The Erosion of Civilizations” not too long ago. I’d highly recommend the book. He argues that neither tilling the soil nor irrigation is sustainable (with the exception of river spill over irrigation, as with the Nile before it was dammed). My guess is that peak dirt in the US came not too long after the Mayflower landed in 1620.
I expect peak dirt is an issue with respect to people being able to feed themselves locally. It is possible to add topsoil by doing one’s own composting in raised beds, but I am not sure that the approach is really scalable to the extent needed. And usually the soil still isn’t very deep, so it dries out quickly.
Do you have a reference with respect to the ecological forecast from 1847?
I listened to Alice Friedemann’s item labelled ‘Peak Soil’ a few years back when it was available as a free download mp3, where she mentioned on the side, that the 1840’s as being peak soil for the USA:
The article in text is at http://energyskeptic.com/2011/peaksoil/
Now I can’t find the mp3….
Thanks! I prefer text to mp3’s anyhow.
Pingback: An Optimistic Energy/GDP Forecast to 2050, Based on Data since 1820 | Sustain Our Earth | Scoop.it
I don’t think your Figure 2 takes into account the amount of energy needed to make the renewable infrastructure (for example to build a solar panel factory, including all the machinery, and to collect 30 annual batches of raw materials, and to make 30 annual batches of panels, and then decommission the factory).
This EI needs to be laid out over time in a spreadsheet, and the ER of the 30 annual batches of panels can then be laid out over the panels’ lifetime. Assuming a panel lifetime of say 30 years, this means a total time frame of about 61 years. Then totaling the net energy (ER – EI) for each year would show that the energy budget for the factory as a whole spends a lot of time at the beginning in the red. This represents energy that must be supplied from fossil fuels to get the system up and running.
The problem gets worse if the number of factories increases at a growing rate. It would eventually pay off energy-wise, but it has a high “energy barrier” at the beginning. This barrier is gets bigger as the ERoEI of the technology chosen gets smaller. Ethanol is the worst technology in this respect, but PV is still very bad. Nuclear is bad, wind is better and hydro (in good locations) is best, but they all have big energy barriers.
Since we won’t make a serious start on renewables until fossil fuels are in desperately short supply, there will not be enough spare fossil energy to complete the transition.
On another point, you say an r-squared of 0.74 is a high correlation. It isn’t. If you make predictions based on something with a correlation of 0.74, you should also calculate the confidence limits of your prediction. They will very quickly shows that the confidence limits are very wide indeed, in fact, unusable.
As I said, this is an optimistic forecast. Solar PV and wind make up only a very small portion of non-fossil fuels, but you are right, solar PV and wind are probably close to the only two that can expand very much. There would be a huge up front investment, with a slow payback. If the systems they are in are not properly maintained (likely because of lack of fossil fuel), the payback may never occur. I believe this is a likely scenario, because, for example, we won’t be able to keep the electric system operating.
I take a first cut at looking at this data, because no one else seems to consider looking at what seems to be obvious. I’ll leave it to others to “pretty things up”, and fix the details that need to fixed.
Don’t assume that we won’t have solar technology that is far superior to solar PV. PV is going to be obsoleted before long with a technology very few understand, but which has been around for 200 years—thermoelectricity. Currently, it’s only about 5% efficient, which makes it pretty insignificant. However, an increase of efficiency to 90% or higher is in the works, being slowed by active opposition from the fossil fuel industry. The oil companies own the Dept of Energy and have been blocking development funds, so that slows everything down. But, this development will remove energy as the stumbling block over the next 5-10 years even if the DOE continues to fight against it. Unfortunately, there are stumbling blocks even larger than energy ahead.
It seems that the big problem is population and food resources, not energy (assuming I’m right about solar PV being obsoleted by efficient TE). Water isn’t a problem if the energy fix is possible because desalination is then made very cheap and practical for turning saline water into drinking water. But, food production is a much more difficult problem because of the finite amount of arable land and the continuing challenge of desertification due to climate change. If we do have a food resource crunch of the magnitude I think is coming (we’re getting a preview now), we are going to have mass starvation to face. When people are faced with starvation, how do they respond? They blame their neighbors and start wars with them (just look at history). Wars may be the practical solution to the population problem. In other words, the most likely path forward appears to be sudden reductions in population due to war. History tells us this is likely solution to the problems we face.
I am afraid you are right about wars being the way population is brought down. You may have read my post Human Population Overshoot-What Went Wrong?
Do you have any references with respect to the improved solar technology? Are there any Lieblig Law of the Minimum issues with it?
You can safely assume that a technology ‘far superior to solar PV’ still won’t generate more electricity than is falling on the earth as sunlight, nor will it store it magically. No will it allow that sunlight to grow plants and food and do the climate thing. Nor will it generate power at night.
The problem is not with the technology,. its with the sunlight. There isn’t enough of it in one place, and unless you want top orbit a solar generator in low sun orbit and send the electricity back by some sort of star trek beam there’s no way round that.
As a rough guide using te UK, the average isolation is 150W/sq meter. Solar panles right now can pull almost 25% or more of that. Say 37.5W per square m,eter.
That’s better than growing crops for biofuel (0.1W/sq meter) or wind farms (2W/sq meter) but is not like a 2 billion watt nuclear power station on a square kilometer of land – 2000W/sq meter or more. And we don’t have ANY storage technology to solve the intermittency problem.
And the cost of in cash and materials of state sized installations- yes, that’s what you are looking at, solar farms the size of entire STATES – is well..I think I’ll leave it there.
It only takes a bit more population increase for human energy needs – even not at USA levels of affluence – to exceed THE ENTIRE ENERGY CONTENT OF THE SUNLIGHT FALLING ON THE EARTH. And since that’s where renewable energy comes from, one way or another, that’s it. Finished. End to growth.
I agree with Dave on this, but when debating these more complex sums in public to the average person it can look like one is opposing renewable energy outright, on the grounds that it is a net energy loser in the long run. And if renewables are a non-goer than nothing is a goer.
I think the context therefore needs to be always kept up front. Renewables can’t deliver society as we know it. Small scale renewables will certainly have to be a feature of human society in the future unless we go back to being hunter gatherers, in which case there are too many of us to even do that.
“I have also assumed that non-fossil fuels (some combination of wind, solar, geothermal, biofuels, nuclear, and hydro) could be ramped up by 72%, so that total energy consumption “only” decreases by 50%”.-Gail
That is a WHOPPER of an assumption Gail.
First off, even if you could ramp up the energy production, with the exception of Biofuels none of these function in the Transportation/Industrial Farming/Mining areas where you don’t just need Energy, you need portable energy that runs Internal Combustion Engines.
A more realistic assumption to me would be MAYBE 30-40% of the loss could be picked up by alternative energy sources. What sort of effect would that generate in your regression analysis?
I agree that is a whopper of an assumption. I thought about pointing out the countries that are closing down their nuclear plants, and the fact that in a lot of countries, the hydroelectric sources are mostly taken.
Actually, though, the number I put in for non-fossil fuels isn’t so huge, compared to the fossil fuels. It only amounts to 22% of the fossil fuel decline. It is because the “base” of the non-fossil fuels is so low, that such a big increase is needed.
Making assumptions about what Might Be is always pretty dicey. My preference is to look back at what WAS, and how that is playing out in real time. You might try this analysis to see how it sits with the optimistic look at GDP/Energy relationships. Look at it from an Anthropoligical perspective rather than an Actuarial one.
Id rather stay with ‘what realistically could be’ than the ‘mights’ or ‘wazzes’…;-)
Thanks! I have written about quite a few of those topics. It seems to me that humans are “k-selected” species. Our natural tendency is to stake out a territory, and defend it. Doing this tends to keep population down. All of the trade and religious teachings have greatly reduced the territoriality, and allowed human population to grow vastly higher than it otherwise would be, out of proportion to other species. (Agriculture helped as well.) See my post Human population overshoot-What went wrong?
Gail, I SAW that post, and in fact if you go back through the Commentariat of it we went Mano-a-Mano there before we got the Diner up and running.
I don;t think Trade and Religion have reduced Territoriality one IOTA here, in fact both circumscribe Territoriality.Trade even moreso than Religion, since control of the monetary system allowed one group of people to monopolize the entire world through the Ownership Paradigm. Religion at least left us with 3 or 4 Majors still battling it out for Hegemony here.
The exponential Growth of Homo Sapiens is the result of becoming wildly successful as the Top of the Food Chain predator in the ecosystem. End result of that is we Predate on each other now, at least until the Beasts of the Earth,aka Pestilence and Disease come in to do the job that no multicellular organism can do at the moment, which is Knock Down the population.
The primary question here is not about GDP OR Energy OR Climate change at all really,it is about whether Homo Sapiens can CONTRACT enough in overall biomass to come back into balance with the rest of the ecosphere. The rest is just tangential and a temporal problem here which will be resolved as always, by the Four Horsemen of the Apocalypse. Famine, Pestilence, War and DEATH. No stopping that from coming down the pipe now.
You are right that being top of the food chain predator has helped up. The population of top of the food chain predators is supposed to be very small, I understand, or they risk wiping out the resources upon which they depend. (Sounds somewhat like our problem now, doesn’t it?)
I was trying to point out that natural population controls that work for animals haven’t worked for us. Part of this is trade. When we trade with others, they are no longer our enemies, so fewer wars, and more people.
Religion can go both ways. “Love your neighbor as yourself” tends to send population up. Starting a war with the next religion over can reduce population. If natural population controls were in effect, (unfortunately) the result would be more wars with neighbors, bringing population down.
